Question

Algebra 2:
If p(x) = 2x2 – 4x and q(x) = x – 3, what is (pºq)(x)?

Answer 1

HI!!

Answer 2

The symbol in between p and q is the composite symbol. I do not know how to solve it.

Answer 3

is that a little circle?

Answer 4

kk we can do it

Answer 5

\[(p\circ q)(x)=p(q(x))\]work from the inside out

Answer 6

\[p(q(x))=p(x-3)\] is the first step to finding it

Answer 7

Okay!

Answer 8

then since
\[p(\color\magenta\heartsuit)=2\color\magenta\heartsuit^2-4\color\magenta\heartsuit\]
you have
\[p(x-3)=2(x-3)^2-4(x-3)\]

Answer 9
